The PicoQuant group was founded in 1996 to develop robust, compact, and easy to use time-resolved instrumentation and systems. Since April 2008 sales and support in North America is handled by PicoQuant Photonics North America Inc. In January 2010, the PicoQuant group was extended by PicoQuant Innovations, which was founded to support the increasing activities in the field of teaching, customer support, and event organization.Today, PicoQuant is known as a company leading in the field of pulsed diode lasers, time-resolved data acquisition, single photon counting, and fluorescence instrumentation. In 2002, we developed the first commercial ultrasensitive fluorescence microscope that permits measurements on the single molecule level. Our instruments are used all over the world. They help to prepare papers in high-ranking journals as well as carrying out routine quality control and production processes of global industrial players. Starting from traditional time-resolved fluorescence detection in bioanalytics, the range of applications is continuously increasing and includes semiconductor quality control, diffuse optical tomography, quantum information processing, optical detector testing, and telecommunications. Due to our easy to use products, researchers can now focus on their problems in biology, medicine, environmental science, or chemistry without needing a large background in physics, electronics, or optics.
